2 Claims.
This invention relates to improvements in, singling preventers. More especially it has to do with a simple automatic device whereby when one of several moving yarns breaks the others are almost simultaneously cut, thereby preventing the running of less than the desired number of yarns.
The invention is particularly applicable to twisting machines of the textile industry but may be employed on any machine where two or more yarns, such as cotton, wool, acetate, rawsilk or rayon, are being moved simultaneously and where it is desired to prevent the continued movement of any yarn should one of the yarns break. The improvements are illustrated in connection with a spooler by which two yarns are drawn from separate spools and wound upon a single spool, a procedure commonly known as doubling. It is highly important to prevent what is called singling, that is the continued winding of one yarn after the other has broken. It is to the prevention of such singling that the invention is directed. I
The principal object is to provide a knife and means for normally holding the knife away from the moving yarns but which upon the breaking of one yarn is adapted to effect movement of the knife so that it will promptly cut the unbroken yarn. It is a feature of the present improve ments that the means employed to prevent singling can be used with yarn drawn from either fixed or rotating spools.
The particular application of the invention shown in the accompanying drawings is purely illustrative and it is intended that the patent shall cover by suitable expression in the appended olaims whatever features of patentable novelty exist in the invention as a whole.
In the drawings:
Figure 1 is a side elevation of a spooler having associated therewith a singling preventer embodying the present improvements;
Figure 2 is a plan view of the same;
Figure 3 is an enlarged side view of the device itself, showing the portion of its parts when the yarns are all running; and
Figure 4 is a similar view showing the positions assumed by the parts when one yarn breaks and the knife is ready to cut the remaining yarns.
Referring more particularly to the drawings, the machine shown for purposes of illustration is a spooler having a rail 1 upon which a series of spindles 2 are mounted on each of which is a spool 3. These spools are rotated by suitable means and draw yarn from a corresponding series of delivery spools. In this particular case, each receiving spool 3 draws yarn from two delivery spools 4 and 5. As shown these spools are fixed and the yarn on each is so wound as to provide a surface S (indicated by the dot and dash lines) corresponding to the surface of a truncated cone, so but it is to be understood that the yarn could be drawn from rotatable spools if desired.
The yarn 6 from one spool and the yarn 7 from the other spool passes through guides 8 and 9 and around tensioning means 10 and 11 through es a guide 12 and thence under a fixed post 13. The latter is mounted on a suitable support 14 on which is also secured a shaft 15. On this is rotatably mounted a knife 16 and a pair of feeler levers 1'7 and 18. Each lever is preferably a light :10 but stiff wire wound once about the shaft 15, with a short arm 17a, (18a) on one side thereof and a long arm 17b (18b) on the other side, the latter arm having a porcelain guide 170 (180) at its end,
When the yarns are moving normally each passes through its respective guides 17c, 18c and thence over another guide 19 to the receiving spool 3. The relative positions of the post 13 and the guide 19 are such that the yarns in passing from one to the other through the guides 17c, 18c hold the latter upward and thus cause the short arms 17a, 18a to be held downward from the knife 16. This knife is so mounted that its own weight tends to swing its cutting edge 16a. downward away from the post 13 and the yarns passing thereunder. Its normal position is determined by some suitable stop 20 on the support 14.
If one of the yarns breaks, as for example yarn 6, as shown in Figure 4, its feeler lever 1'7 immed'iately rotates about the shaft 15. The leverage of the weight of the long arm 17?) and porcelain guide 17c acts to swing the short arm 1711 up against the knife with an appreciable force and r thus causes the knife to rotate and bring its cut-- ting edge into contact with the post 13. The unbroken yarn 7 is thus severed and singling is prevented.
If more than two yarns are being drawn from the delivery spools, there would be provided a feeler lever for each yarn, and each would be effective upon the breakage of its particular yarn to move the knife to cutting position and thus effect the prompt severance of all the remaining yarns.
The device is exceedingly simple and yet highly effective, due primarily to the fact that it operates to positively cut the unbroken yarns immediately upon the breakage of one of them.
I claim as my invention:
1. Means for stopping the movement of two or more moving yarns comprising a fixed post past which the yarns move; a movable knife pivotally mounted beyond said post in the direction of travel of said yarn, normally positioned clear of said post and yarns but adapted to be swung toward said post to bring its cutting edge into engagement with the yarns so that further travel of the yarn would tend to enhance said engagement; and means engaging the moving yarn and positioned thereby for moving said knife toward said post upon the breaking of a yarn whereby the remainder of the yarns are severed.
2. Apparatus of the character described comprising a support; a post fixed thereon past which two or more yarns are arranged to move; a shaft fixed on said support beyond said post in the direction of travel of said yarn; a knife rotatably mounted on said shaft tending to swing away from said yarn and post but adapted to be swung toward said post to clamp the yarn between the cutting edge and the post; a feeler lever for each yarn rotatably mounted on said shaft having an arm engaging its respective yarn and having another arm arranged to engage said knife; said lever being so disposed that upon the breaking of its respective yarn, the lever swings into engagement with said knife and rotates it toward the said post whereby its cutting edge severs the unbroken yarns.
